The nature of the tensions between VanderZanden and the other Lyft execs remains unclear.

"Eighteen months ago, Travis joined the Lyft team as part of the Cherry acquisition to help scale our operations," said Erin Simpson, Lyft's director of communications. "We've talked about the future and all agree that Travis will move on as we move forward into the company's next chapter of growth. We appreciate everything he's done here and wish him the best in his next adventure."
